Definitions

  • the invention relates to a tie rod for connecting opposite sections of a casting formwork, especially formwork for concrete. More particularly, the invention relates to a tie rod formed with a mid portion which is arranged to form supporting abutment surfaces against the internal surfaces of the formwork to maintain a predetermined distance between the formwork sides, and the mid portion is arranged to be fixed in the set casting material to form anchoring points in the concrete in such a way that good adherence is ensured between the concrete and the tie rod in order to prevent moisture from entering along the rod and cause damage to the concrete, and by good thermal properties to prevent condensation at the end portion of the tie rod, the tie rod being formed in one piece of a non-corrosive material, preferably a composite material.
  • the casting material is described as "concrete”, and in this description there are also used other casting-process-related terms known from the casting of concrete. Nevertheless, the invention is not limited to applying only to formworks, which are to be filled with concrete, but also relates to formworks, which are used when pouring building structures with other casting materials.
  • tie rods When concrete is poured, tie rods must be used to keep the formwork in position, that is to say to prevent the distance between two opposite sections of formwork which are to define a wall, for example, from changing when the formwork is loaded in the supporting of or by the pressure from the plastic concrete which is filled into the formwork.
  • Tie rods are set with relatively regular spacing and fix the opposite formwork sections with a distance determined by the dimension of the tie rod.
  • the tie rods are locked with wedges to braces extending along the external sides of the formwork.
  • Prior art tie rods are formed of steel with spacers which are arranged to bear on the internal wall surface of the formwork sections, made of plastic, slipped over the tie rod in the production process and positioned axially on the tie rod, each bearing on a respective widened portion of the tie rod or an equivalent item.
  • the projecting end portions of the tie rods are broken by bending them at a weakened portion located at the spacers.
  • the surface of fracture is exposed in the wall surface, and the spacers, which are often of a conical shape with their widest portions facing outwards, often fall out.
  • the tie rod or, more accurately, the remainder of the tie rod, which is inside the concrete structure forms an entry gate for moisture.
  • the moisture penetrates the concrete structure and comes into contact with the reinforcement, which lies, in part, immediately adjacent to or in direct contact with the tie rod.
  • the reinforcement corrodes, the reinforcing strength is weakened, the adherence between the concrete and reinforcement is weakened and the concrete scales off due to corroded steel (rust coating) swelling relative to non-corroded steel. Corrosion also occurs on the tie rod.
  • the tie rods In concrete structures which are to retain a liquid, that is prevent the liquid from entering or escaping, the tie rods will often be a source of leakage along the tie rods because of, among other things, poor adherence between steel and concrete.
  • NL 9101666 A discloses a shuttering arrangement for concrete, comprising: two shut-tering walls spaced apart; and one or more rods or wires which are attached to the shuttering walls and are made of an aramid fibre composite. Enlarged end portions are formed to engage with removable fasteners. A separate helix shaped distance element envelope the mid portion of the rod. NL 9101666 A does not disclose integrated abutment surfaces arranged to rest supportingly on the internal side surface of the shuttering.
  • the invention has as its object to remedy or reduce at least one of the drawbacks of the prior art.
  • the invention relates to a tie rod formed of non-corrosive materials, preferably composite materials, in which a mid portion, exhibiting opposite abutment surfaces arranged to rest supportingly on the inside of a formwork section, and a rod stem forms a continuous structure.
  • the mid portion may also include supporting and securing portions for other building materials and also include elements, which increase the adherence to the surrounding concrete and/or reduce the possibility for water to enter along the tie rod.
  • the projecting rod end portions may be cut off at any position with a cutting tool suitable therefore, for example cutting pliers.
  • tie rod according to the invention exhibits improved properties in several areas:
  • Any fasteners for securing building materials to the tie rod are preferably also formed of a non-corrosive material.
  • the invention relates to a tie rod for joining opposite side sections of a casting formwork, the tie rod being provided with a mid portion and two rod end portions, and there being formed in the transitions between the mid portion and either rod end portion at least one abutment surface which is arranged to bear supportingly on an internal surface of the side sections, the rod end portion including rests for wedges for securing the side sections of the casting formwork, characterized in that the tie rod includes a stem of large tensile strength and a surrounding mantle, the mid portion and the mantle of the stem being formed as a continuous structure, the stem, mantle and mid portion being formed of non-corrosive materials.
  • the tie rod is preferably formed of a composite material, the stem being fibrereinforced in the axial direction of the tie rod.
  • the mantle and the mid portion are advantageously formed of the same type of material.
  • the mantle and the mid portion are preferably joined by fusion of the material forming the mantle and the material forming the mid portion. Alternatively the mantle and the mid portion are joined by gluing.
  • the mid portion is preferably provided with means for non-releasable engagement with a surrounding casting material when this has been poured into the formwork and has set.
  • the mid portion and the stem portion surrounded by the mid portion is advantageously arranged to form a watertight, non-releasable, through plug in a completed cast structure.
  • the abutment surface is preferably formed by the mid portion exhibiting a widened cross-section towards its abutment portions.
  • At least one portion of the mid portion advantageously exhibits a cross-section exhibiting, when the cross-section lies perpendicularly to the centre axis of the tie rod, a non-circular shape.
  • the mid portion is advantageously provided with a plurality of concentric cross-sectional widenings.
  • the mid portion is advantageously arranged to receive and fix one or more locking means for a plate-shaped building material, for example an insulating material, substantially annular grooves being complementary to a portion of the locking means.
  • the locking means are preferably formed of a non-corrosive material.
  • the mid portion of the tie rod advantageously includes one or more means arranged to receive a reinforcing means, preferably in the form of one or more substantially annular grooves.
  • the substantially annular grooves advantageously have a trapezoidal cross-section with the smallest width at the bottom of the groove, the side edges of the groove exhibiting the same angle of inclination relative to the centre axis of the tie rod.
  • the mid portion of the tie rod is advantageously arranged to receive one or more securing means for securing the reinforcing means.

  • the thermal conductivity of the tie rod is advantageously smaller than the thermal conductivity of the surrounding completed cast structure.
  • a tie rod 1 includes a stem 2 with a mantle 2a, a mid portion 3 and two rod end portions 5a, 5b. At either one of the transitions between the mid portion 3 and the rod end portions 5a, 5b the mid portion exhibits a cross-sectional widening 7a, each forming an abutment surface 7.
  • the tie rod 1 is formed of a composite material, the stem 2 being reinforced in a manner known in itself with a fibre material of large tensile strength and surrounded by a bonding material forming the mantle 2a of the stem 2.
  • the mid portion 3 may be formed of the same type of material as the mantle 2a.
  • the cross-sectional widening forms a frustum of a cone, a bottom surface 7b facing the mid portion 3.
  • the centre axis of the cone coincides with the centre axis of the tie rod 1.
  • a top surface faces the adjacent rod end portion 5a, 5b, respectively, and is placed perpendicularly to the centre axis of the tie rod 1, forming the abutment surface 7.
  • the bottom surface 7b exhibits a non-circular shape, four segment surfaces 7c lying parallel to the centre axis of the tie rod 1 in the direction towards the abutment surface 7 and extending into a side surface 7d. Two by two opposite segment surfaces 7c are parallel to each other, the bottom surface 7b forming a square with rounded corners.
  • the abutment surface 7 is formed as a first four-armed cross 57b.
  • a second four-armed cross 57a of larger arm length is formed at a distance from the first cross 57b, and four ribs 58a projecting radially and diametrically opposite, extend axially between the arms 59a, 59b of the crosses 57a, 57b.
  • this embodiment exhibits several concentric, circular cross-sectional widenings forming securing and sealing ribs 58b.
  • the mid portion 3 is joined in a sealing manner to the stem 2, liquid, for example water, being unable to enter in an axial direction from the end portion 5a, 5b towards the mid portion 3 due to the passage of the stem 2 through the mid portion 3 forming a tight connection.
  • the tight connection is formed by fusion of the materials of the mantle 2a and the mid portion 3 in the production, or by joining them with, for example, glue forming a watertight joint between the stem 2 and the mid portion 3.
  • Either rod end portion 5a, 5b is provided at its outer end with a projecting rest 9 for a wedge device 11 for securing the side sections 23a, 23b of a formwork 21.
  • the mid portion 3 is provided with several grooves 3a extending round the entire periphery of the mid portion and arranged to receive a locking disc 13 for positioning and fixing a plate-shaped cast-in material 15, for example an insulating material.

  • the thickness of the locking disc 13 forms, at least at the centre hole 13b, a press fit with the side edges of groove 3a of the mid portion 3, or the periphery of the centre hole 13b forms a press fit with the bottom surface of the groove 3a.
  • the mid portion 3 is also provided with several grooves 3b extending round the entire periphery of the mid portion and having a transversal profile which is arranged to receive a reinforcing means 25 in the form of reinforcing steel or similar, the cross-section of the groove being trapezoidal, for example.
  • the tie rod 1 may expedient also include a securing disc 17 which is arranged to be secured to a cut rod end portion 5a, 5b projecting from a set casting material 31, for example a concrete wall, after the formwork 21 has been removed, the securing disc 17 being provided with a number of radially oriented, resilient fingers 17a extending from a circumferential portion 17b and in a radial direction towards a centre opening 17c, each finger 17a being separated from an adjacent finger by a slot 17d extending in a radial direction from the centre opening 17c to a circular opening 17e in the circumferential portion 17b of the securing disc.
  • the centre opening 17c exhibits a diameter, which is smaller than the diameter of the rod end portions 5a, 5b to ensure that the securing disc 17 is retained in a prescribed position on the rod end portion 5a, 5b in that the fingers 17a are under tension.
  • At least the projections 9 and the stem 2 of the tie rod 1, that is to say the rod end portions 5a, 5b and the through core of the mid portion 3, are formed of a composite material of a tensile strength which is great enough for absorbing the relevant tensile loads to which the tie rod 1 for a formwork 21 is subjected during installation and during pouring of the casting material 31, for example concrete, into the formwork gap.

  • the locking disc 13 and the securing disc 17 are advantageously formed of a non-corroding material, for example a plastics material.
  • the tie rod 1 is installed in a manner known per se as the formwork 21 is being built, side sections 23a being put together before the reinforcing means 25 then being positioned and locked relative to each other and the formwork 21.
  • Insulating material 15, if any, for casting in, is fixed by means of the locking discs 13 before the opposite side sections 23b are mounted and the formwork is closed and secured by fitting the wedge devices 11 to the tie rods 1 within the projections 9 and tightening the tie rods 1.
  • the abutment surface 7 rests supportingly on an internal side surface 23c of the side sections 23a, 23b of the formwork 21.
  • the formwork 21 is removed in a manner known per se, and the projecting rod end portions 5a, 5b of the tie rods 1 are cut off.
  • rod end portions 5a, 5b are to be used for securing plate-shaped building materials 33, for example insulating plates, on one or both sides of the completed cast structure 31, these are secured by slipping the securing discs 17 onto the rod end portions 5a, 5b into abutment on the plates 33 after the projection 9 and suitable lengths of the rod end portions 5a, 5b have been cut off.
  • plate-shaped building materials 33 for example insulating plates
  • building materials are to be secured by screwing or nailing, for example, this may be done by securing the fasteners to the mid portion 3 through the centre of the abutment surface 7 which is level with the outer surface of the cast structure 31 and formed by the cut stem 2.
